Comedian John Mulaney is surrounding himself with some comedy heavyweights on his NBC pilot. After lengthy negotiations, Elliott Gould and Martin Short are set to co-star opposite Mulaney in his untitled multi-camera comedy, from Lorne Michaels, 3 Arts and Universal TV. Written/exec produced by Mulaney and exec produced by 30 Rock‘s Robert Carlock, the project  is a young ensemble loosely based on Mulaney’s life. It centers on John (Mulaney), whose naïve, and often pointless, desire to “be a good person” challenges his friendship with his roommates Jane and Seymour. APA-repped Gould plays John’s gay neighbor. WME-repped Short plays Lou, a game show host John writes jokes for.
